I understand, but try to see this from a different point of view:

There are people on MHF who are trying to offer *help* (that's what the "H" stands for in MHF). If you want help, I don't think it's unreasonable that you be asked to show some work. Furthermore, this most recent post is very off-putting. It may be that English isn't your native language, but you might still try to clean it up a bit!

Finally, here's a site that will help you format your questions in a pretty way. Online LaTeX Equation Editor - create, integrate and download

....................

Now, #4 looks like it's "separable"

We get $\displaystyle \frac{dv}{(2v)^2 + 36} = t^2 \cdot dt$

Can you integrate both sides? A trig substitution might help on the left... - Oct 17th 2011, 11:41 AMkmankishRe: Please help-Integartion
yes i understand, thanks for the suggestion am i right in thinking the rhs goes to

http://latex.codecogs.com/gif.latex?...\frac{v}{3})+c

if i have c on both sides can i take it as c overall? - Oct 17th 2011, 11:46 AMTheChazRe: Please help-Integartion
